The spelling of the word "bargo" can be explained using the International Phonetic Alphabet (IPA) transcription /ˈbɑːɡəʊ/. The first syllable, "bar", is pronounced with the vowel sound /ɑː/, which is a longer version of the "a" sound in the word "cat". The second syllable, "go", uses the diphthong /əʊ/, which is a combination of the vowel sounds /ɔː/ and /ʊ/. This spelling can help non-native English speakers understand the correct pronunciation of this word.
